Description

Description Staple refill Technical field

The present invention relates to a stable refill for accommodating a sheet-shaped connected stable wound in a roll shape. Background technique

Conventional staple refills for accommodating sheet-like connected staples wound in a roll form include, for example, a stapler body disclosed in Japanese Patent Application Laid-Open No. 9-136271 (Patent Document 1). Alternatively, it has a refill body detachably attached to a cartridge installed in the stapler body. The refill body has a storage section for storing the sheet-shaped misaligned staples, an outlet for discharging the sheet-shaped connection stable stored in the storage section, and a front end of the sheet-shaped connection stable stored in the storage section. There is an outlet for the outlet. The lead-out path is formed substantially linearly, and is formed along the lower surface in the storage section. At the upper part of the lead-out path, a metal backstop member formed separately from the refill body is attached. The sheet-like connecting staple is formed by connecting a large number of linear stables side by side while contacting them side by side, and applying a bonding agent on the upper surface to connect them in a belt shape. Further, the sheet-shaped connecting staple is adhered in the longitudinal direction at the center of the upper surface with an adhesive tape to prevent the linear staples from coming off. This sheet-shaped connecting staple is wound in a roll shape so that the upper surface faces outward, and stored in a staple refill.

A stay for accommodating the conventional rolled sheet-like connected staples The refill for pull is stored in the storage section of the refill main body so that the leading end of the sheet-like connecting staple is on the lower side, and the leading end of the sheet-like connecting stable is placed along the lower surface of the storing section and the lead-out path. It is stretched straight. When the leading end of the sheet-like connected stable is sent out from the discharge port by the feeding means such as the feed claw and feed roller provided on the stapler body, the sheet-like shape is drawn into the linearly drawn-out part. There is a problem in that the entire connection stable is mounted, and the weight of the sheet-like connection stable is applied to the feeding means as a load. Also, when the sheet is pulled out, the entire sheet-like connecting stable moves forward, so that the sheet-like connecting stable comes into contact with the inner surface of the storage section, and a frictional action exerts a load more than a predetermined value. There was a problem that it became difficult to feed out the tip of the shape-linked stable.

Also, in the conventional staple refill, when the reversing prevention member is slid in contact with the straightened extension portion and is pulled out to the discharge port side, the reversing prevention member extends radially to the discharge port, and the sheet is not slid. If the drawer is not likely to be pulled back toward the storage section without obstructing the drawer, the back-up prevention member is locked in the connection recess between the stables of the sheet-like connection stable, and the sheet-like connection is made. Prevent stable pullback. As described above, the reverse movement preventing member is always in sliding contact with the sheet-shaped connecting stable. However, if the contact pressure at the time of this sliding contact is too strong, the load applied to the feeding means of the sheet-like connecting stable becomes large, If the contact pressure at the time of this sliding contact is too weak, the pull-back resistance of the sheet-like connecting stable becomes small, so that there is a problem that it is difficult to adjust the reverse movement preventing member.

Further, the sheet-like connecting stable is arranged such that the sending-out means is pressed forward and engaged with the lower surface and is sent forward, and as described above, an adhesive is applied to the upper surface side, and an adhesive tape is provided at the center of the upper surface in the longitudinal direction. Affixed to . In the conventional staple refill, the back-stopping member slides on the upper surface of the sheet-shaped connecting staple to which the adhesive is applied, so that the back-stopping member may slip and fail to function. In addition, the back-stopping member slides on both sides of the sheet-like connecting stable with the adhesive tape interposed therebetween. However, if one of the back-stopping members does not function, the sheet-like connecting stable may be bent. was there. In addition, there was a problem that it was difficult to adjust both of the anti-retro members to function similarly. In addition, since the backstop member is manufactured separately from the refill body, it is troublesome to attach it to the refill body, and when installing it, adjustment may be required as described above, so anyone can easily refill. There was a problem that it could not be incorporated into the main unit. In addition, conventional staple refills incorporate a back-stopping member made of a metal material, and must be separated for each material when discarded. There was a problem. .

In the conventional staple refill, when a sheet-shaped connected staple wound in a roll is stored in the storage section of the refill body, the entire outer periphery of the sheet-shaped connected staple is stored in contact with the bottom of the storage section. Is done. When the sheet-like connecting stable is pulled out to the discharge port side, the entire circumference of the sheet-like connecting stable rotates while sliding on the bottom surface of the storage portion, so that the frictional resistance is large, and the sheet-like connecting stable is sent out. There was a problem that such a load was large.

In the conventional staple refill, a sheet-shaped connected staple wound in a roll is stored in the storage section of the refill body. Could be loosened. In addition, the inside of the opaque refill body cannot be seen. There was a problem that it was not possible to check and check the remaining amount.

The present invention has been made in view of the above-described problems, and can be stored in a V-fill storage portion such that a leading end of a sheet-shaped connecting stable wound in a roll shape is located above, A first object of the present invention is to provide a staple refill which can reduce a load on a feeding means of a stapler main body since a sheet-like connecting stable is not placed on a drawer portion which is pulled out and fed. In addition, the lead-out path is curved upward from the discharge port toward the inside of the storage section, and a return-prevention member is formed in the lead-out path. When the sheet-shaped connecting stable is sent out, the return-prevention member is inclined downward. Providing a staple refill that weakens the locking force and inclines upward when the sheet-like connecting stable is pulled back, increasing the locking force and eliminating the need to adjust the anti-reverse member. This is the second purpose.

Also, the back-up preventing member is not brought into sliding contact with the upper surface of the sheet-like connecting stable to which the adhesive is applied and the adhesive tape is stuck, but is provided on the lower surface of the sheet-like connecting stable with which the feeding means of the stapler body comes into contact. A stable refill that does not have a risk of bending and sending out the sheet-like connecting staples because the sheet-like connecting staple can be slid into contact with the sheet-like connecting staple to reliably lock the sheet-like connecting staple. Is the third purpose. Furthermore, since the anti-retro member is molded integrally with the refill, the labor for attaching the anti-retro member to the refill can be omitted, and a stable refill that anyone can easily assemble into the refill can be provided. It is the purpose.

Furthermore, in the refill storage section, a ridge is provided on the sheet-like connected staple wound in a roll shape so as to be in sliding contact with the outer periphery, thereby reducing the area in contact with the outer periphery of the sheet-like connected staple to reduce frictional resistance. And provide a stable refill that smoothes the rotation of the seat The fifth purpose. Furthermore, the staple can be used to hold the rolled sheet-shaped connecting stable stored in the storage part of the refill so as not to move, and the staple is formed with an opening through which the inside of the storage part can be checked. A sixth purpose is to provide a refill for use. Disclosure of the invention

The lead-out path 45 guides an upper guide surface 47 that guides the upper surface S2 of the sheet-like connecting stable S and a lower surface S3 of the sheet-like connecting stable S. It has a lower guide surface 48. The upper guide surface 13 a of the second guideway 42 is connected to the inner surface 41 of the storage portion 40. The lower guide surface of the second guide path 42 is formed by a curved surface 26 of the guide projection 25 protruding into the storage section 40 on the side of the discharge port 46. The reverse movement preventing member 31 is formed so as to protrude from a surface 26 of the guide projection 25 on the discharge port 46 side. A surface 27 of the guide projection 25 on the storage section 40 side is formed to be curved so as to guide the sheet-like connecting stable S stored in the storage section 40.

Also, the inner surface of the storage portion 40 of the refill 1 is in slidable contact with the outer periphery of the sheet-shaped connecting staple S wound in a roll shape, and a ridge 20 for smooth rotation of the sheet-shaped connecting staple S is provided. , 35 are provided. The refill 1 has an opening 8 communicating with the storage section 40.

Further, the staple refill will be described in detail. The refill body 2 of the staple refinole 1 includes an upper case 3 and a lower case 5 detachably fixed to the upper case 3 as shown in FIGS. The upper case 3 is integrally formed of a synthetic resin, and includes an upper wall 6, a left wall 7 provided at a left end of the upper wall 6, and a right wall 9 provided at a right end of the upper wall 6.

The upper wall 6 includes an upper half-cylindrical wall 11, a vertical wall 12 having an upper end connected to the front end of the upper half-cylindrical wall 11, and a curved wall 13 having one end connected to the lower end of the vertical wall 12. And a horizontal wall 15 having a rear end connected to the other end of the curved wall 13. The left wall 7 and the right wall 9 are composed of circular walls 7a, 9a and lower walls 7b, 9b connected to the lower ends of the circular walls 7a, 9a and extending in a substantially horizontal direction. . The lower walls 7b, 9b project downward from the horizontal wall 15. Lock holes 14 and 14 are formed in the lower walls 7 b and 9 b.

On the upper part of the upper semi-cylindrical wall 11, a gripping arm 18 extending rearward is formed. On the upper surface of the curved wall 1 3, there are ribs 1 for reinforcing the curved wall 1 3 9 are formed. An opening 8 is formed at the rear of the upper half-cylindrical wall 11. Further, the inner surface of the upper wall 6 of the upper case 3, that is, the inner surfaces of the upper semi-cylindrical wall 11, the vertical wall 12, the curved wall 13 and the horizontal wall 15 are guides for guiding the sheet-like connecting staple S. A ridge 20 is provided.

As shown in FIGS. 3 and 4, the lower case 5 is integrally formed of synthetic resin and has a lower wall 21 similarly to the upper case 3. The lower wall 21 is composed of an arc-shaped wall 22 formed in an approximately 1/4 arc shape, and a straight wall 23 having a rear end connected to a front end of the arc-shaped wall 22. A substantially mountain-shaped guide projection 25 is formed on the straight wall 23. The surface 26 of one of the guide protrusions (guide protrusions) 25 (the discharge port 46 side) is formed so as to form a substantially constant gap with the lower surface 13 a of the curved wall 13 of the upper case 3. It is curved. The surface 27 on the other side of the guide projection 25 (on the storage section 40 side) is curved so as to draw an arc similar to the arc-shaped wall 22. The top 29 of the guide projection 25 is formed in a semicircular shape.

A cutout portion 30 is formed at a substantially intermediate portion of the guide projection 25. The straight wall 23 is provided with a claw-shaped back-up prevention member 31 which is located inside the cutout portion 30 and protrudes from the curved one surface 26 by body formation. The straight wall 23 has a substantially U-shaped cutout recess 32 formed at the front, and the rear is formed so as to extend to the rear of the arc-shaped wall 22. Also, on the inner surface of the lower wall 21 of the lower case 5, that is, on the inner surfaces of the arc-shaped wall 22, the guide projection 25, and the straight wall 23, a guide band (a guide band for guiding the sheet-like connecting stable S) is provided. (Protrusions) 3 5 are provided. On both sides of the lower wall 21, locking claws 36, 36 that are detachably locked in the locking holes 14, 14 of the upper case 3 are formed.

When the lower case 5 is fitted between the lower wall 7b of the left wall 7 of the upper case 3 and the lower wall 9b of the right wall 9, the staple refill 1 36 is locked in the locking holes 14 and 14 of the upper case 3, and the refill body 2 is assembled. In this assembly, as shown in FIG. 3, the leading end S1 of the sheet-like connecting staple S in the counterclockwise winding state is positioned at the upper part, and the sheet-like connecting staple S is placed in the upper case 3. When the sheet is accommodated, the sheet-shaped misconnected staple S is placed in the lower case 5.

The refill body 2 has the upper half-cylindrical wall 11 and the vertical wall 12 of the upper wall 6, the arc-shaped wall 22 of the lower case 5, and the other of the guide projections (guide projections) 25. The cylindrical storage room is formed by the surface 27 of the part 40 side), the left wall 7

40 are formed. The sheet-shaped connecting staple S is positioned on the lowest straight wall 23 by the arc-shaped wall 22 of the lower case 5 and the other surface 27 of the guide projection 25.

The refill body 2 has a curved surface 13 of the upper case 3, a lower surface 13 a of the upper case 3, a guide projection 25 of the lower case 5, a surface 26 on one side (the outlet 46 side), and a left wall 7.ぴ The right wall 9 forms a second guideway 42 that curves gently upward. The second guide path 42 is curved upward toward the storage section 40 and communicates with the storage section 40. The refill body 2 ′ has a substantially linear shape by the lower surface 15 a of the horizontal wall 15 of the upper case 3, the upper surface 23 a of the straight wall 23 of the lower case 5, the left wall 7 and the right wall 9. The first guide path 43 formed at the end is formed. That is, the guide path 45 is formed by the first guide path 43 and the second guide path 42. A discharge port 46 is provided at the front end of the lead-out path 45, and discharges sequentially from the leading end S 1 of the sheet-like connecting stable S.

The lead-out path 45 has an upper guide surface 47 for guiding the upper surface S2 of the sheet-like connected staple S, and a lower guide surface 48 for guiding the lower surface S3 of the sheet-like connected staple S. The upper guide surface 47 is formed by the lower surface 15 a of the horizontal wall 15 of the upper case 3 and the lower surface 13 a of the curved wall 13 of the upper case 3. The The lower guide surface 48 is formed by the upper surface 23 a of the straight wall 23 of the lower case 5 and the surface 26 of one of the guide protrusions 25 (on the discharge port 46 side). Two guide projections 20 are provided on the surface of the upper guide surface 47 in the lead-out path 45 along the moving direction of the sheet-like connected staples S. The guide ridge 20 is a band-like projection that protrudes slightly higher from the surface of the upper guide surface 47 toward the sheet-like connecting staple S side, and is formed between the upper guide surface 47 and the sheet-like connecting staple S. By reducing the contact area of the staples S, the sliding resistance during the movement of the sheet-like connected staples S is reduced, and the sheet-like connected staples S are smoothly drawn out. A cutout recess 32 is provided at a position of the lower guide surface 48 facing the horizontal wall 15 of the upper guide surface 47. The notch concave portion 32 is a portion for bringing the feed claw (feed roller) of the stapler body 50 into contact with the lower surface S3 of the sheet-like connecting staple S, and the sheet-like connecting stable S is formed by the notch concave portion 32. It is drawn from the storage section 40 and sent to the discharge port 46.

The reverse movement preventing member 31 protrudes into the second guide path 42, and the tip 31 a extends to near the lower surface 13 a of the curved wall 13. The reverse movement preventing member 31 can be bent by the elasticity of the synthetic resin material. The tip 3 la of the back-up preventing member 3 1 is in sliding contact with the lower surface S 3 of the sheet-like connecting staple S to lock the connection recess between the staples of the sheet-like connecting staple S, so that the backward movement toward the storage section 40 is performed. To prevent The back-up preventing member 31 may be provided at an angle as shown in FIG. 6 (a), may be provided in a substantially L shape as shown in FIG. 6 (b), or may be provided as shown in FIG. 6 (c). As shown in the figure, the shape can be substantially n-shaped, and the shape is not particularly limited. As described above, the anti-backward protrusion 31 is formed in a claw shape, and during transportation, the tip 3 la has a sheet-shaped connecting stable S (particularly a portion S 5 to be pulled out) on the lower surface 13 a side of the curved wall 13. ) Is pressed strongly. For this reason, the stable There is no possibility that the sheet-shaped connecting stable S is pulled out from the refill 1 for use. Also, when the staple refill 1 is set, the portion protruding from the lower wall 21 is returned into the refill, so that the reverse movement preventing member 31 rotates counterclockwise. Due to this rotational displacement, the tip 31 a of the retrograde prevention member 31 slightly retracts from the lower surface 13 a of the curved wall 13, so that the pressing force on the sheet-like connecting staple S is reduced. Therefore, the movement resistance of the staple S in the supply direction is reduced, and the staple S is smoothly fed.

A drawer tape (not shown) provided at the leading end S1 of the sheet-like connecting stable S is taken out from the outlet 46, and when the drawer tape is pulled, the drawer tape is provided in the storage chamber 40 for the staple refill 1. The sheet-like connection stable S thus rotated rotates, and its tip is located at the discharge port 46. Attach the staple refill 1 to the cartridge 51 which is detachably attached to the stapler body 50, and attach the cartridge 51 to the stapler body 50. When the stapler body 50 is driven, the leading end S1 of the sheet-like connecting stable S is intermittently pulled out to the driver side by a feeding means (for example, a feeding claw, a feeding roller, or the like). Since the roll-shaped winding portion S4 of the sheet-shaped connecting stable S is not placed on the portion S5 to be drawn out, the load on the feeding means is small. In addition, the entire outer periphery of the roll-shaped winding portion S4 of the sheet-like connected staple S does not necessarily contact the inner surface of the storage chamber (storage portion) 40, and a part thereof is formed with guide ridges 20 and Since it comes into contact with the guide band (protrusion) 35, the contact area is small and the frictional resistance is small, so that the load on the feeding means is further reduced.

Further, when the leading end S1 of the sheet-like connected stable S is pulled out by the feeding means of the stapler body 50, as shown in FIG. 8 (a), the drawn-out portion S5 becomes the outlet path 45. Close to the upper guide surface (the lower surface 13a of the curved wall 13), the tip 31a of the back-up prevention member 31 is a sheet-like connecting stapler. Since the roller S slightly comes into sliding contact with the portion S5 from which the sheet S is pulled out, the load is not so much applied to the feeding means, and the sheet-shaped connection stable S can be reliably fed. Further, when the leading end S1 of the sheet-shaped connecting stable S is pulled back by the weight of the roll-shaped winding section S4 in the storage section 40, as shown in FIG. S5 comes into close contact with one surface 26 of guide projection 25, and tip 31a of backstop member 31 protruding from one surface 26 securely locks sheet-like connecting stable S.

In the staple refill 1, as the sheet-like connected staples S are pulled out, the roll-shaped winding portion S4 becomes smaller, but as shown in FIG. Since the drawn-out portion S5 of the sheet-like connected staple S is lifted and then led out to the lead-out path 45, it functions in the same manner as described above. Since the top portion 29 of the guide projection 25 is formed in a semicircular shape, the sheet-like connecting staple S can be smoothly guided.

As described above, the staple refill 1 is provided in the housing 4

0, the leading end S1 of the sheet-like connected staple S wound in a valley shape can be stored so as to be on the upper side.

Since the roll-shaped winding part S4 is not placed on the drawer part S5 when the paper is sent out from 46, the load on the feeding means is small.

In the conventional staple refill, the backstop member slides on the linearly extended portion of the sheet-like connected staple, and it is difficult to adjust the contact pressure of the backstop member at the time of the sliding contact. As described above, the stable refill 1 uses the curved lead-out path 45, and the locking force of the reverse movement prevention member 31 when the sheet-shaped connected stable is pulled out and when the sheet is connected is different, At the time of retraction, the locking force of the reverse movement preventing member 31 is improved, so that it is not necessary to adjust the contact pressure of the reverse movement preventing member 31. Further, the refill 1 for staples is a sheet in which the anti-reverse member 31 is not coated with the adhesive and the adhesive tape is not stuck in the longitudinal direction, similarly to the feeding means of the stapler body 50. The lower surface S3 of the sheet-like connecting staple S is pressed into engagement with the lower surface S3, so that it is possible to reliably prevent the sheet-like connecting staple S from moving backward, and to dispose the reverse movement preventing member 31 approximately at the center of the lower surface S3. Therefore, the sheet-shaped connecting stable S can be engaged in a well-balanced manner.

Since the staple refill 1 has the back-stopping member 31 integrally molded, there is no need to integrate the back-stopping member made of a metal material into the refill body as in the past, and anyone can easily assemble it. The weight and cost of the refill body 2 can be reduced, and it is not necessary to separate and dispose of each material, so disposal is easy.

[The invention's effect]

The staple refill according to the present invention can be stored in a storage portion of a refill main body such that a leading end of a sheet-like connected staple wound in a roll shape is on an upper side, and a sheet is pulled out and fed out to a drawer portion. Since the shape connection stable is not put on, there is an effect that the load on the feeding means can be reduced. In addition, in the stable refill according to the present invention, since the lead-out path is curved upward from the discharge port toward the inside of the storage unit, and the curved lead-out path is provided with a backflow preventing member, the sheet-shaped connecting stable is fed out. When the sheet-like connecting stable is pulled back, the locking force can be increased, and the adjustment of the reverse movement preventing member can be eliminated.

In the staple refill according to the present invention, the anti-reverse member does not slide on the upper surface to which the adhesive is applied and the adhesive tape is adhered, but slides on the lower surface of the sheet-like connecting stable on the same side as the feeding means. Since the contact is made in contact, the back-stopping member is less slippery, and the sheet-like connecting staple can be securely locked. Further, since the lower surface of the sheet-shaped connecting staple can be slid in contact with the center, the back-stopping member can be locked to the sheet-shaped connecting staple in a well-balanced manner, and the possibility of the sheet-shaped connecting staple being bent is extremely small. Has the effect of being able to Furthermore, in the staple refill according to the present invention, since the anti-return member is formed integrally with the refill main body, the labor for attaching the anti-retro member to the refill main body can be omitted, and anyone can easily assemble the refill main body. This has the effect. In the staple refill according to the present invention, a ridge is provided on the inner surface of the storage portion so as to be in sliding contact with the outer periphery of the rolled sheet-shaped connecting stable, and the entire outer periphery of the sheet-shaped connecting stable is provided. Since the contact is not made to contact the bottom of the storage part but to a part of it, the contact area is small, and the sheet-shaped connecting stable can be smoothly rotated. .

Since the opening for communicating with the storage section is formed in the refill main body according to the present invention, the sheet-shaped connection stable stored in the storage section does not move during transportation. A holding member such as a cushioning member can be attached using the opening, so that the leading end position of the sheet-like connecting stable can be prevented from shifting, and furthermore, using the opening, the sheet-like connecting stable can be used. This has the effect of being able to check the status such as the remaining amount of the battery.
